The agreement reached between the six world powers and Iran to lift the decade-long sanctions will prevent Tehran "from obtaining a nuclear weapon", US President Barack Obama said on Tuesday.
Obama said the agreement met the goals they had in place throughout their talks, but the deal was not about trust rather about inspection.
"Today, after two years of negotiation, the US together with the international community has achieved something that decades of animosity has not: a comprehensive long-term deal with Iran that will prevent it from obtaining a nuclear weapon," CNN quoted Obama as saying from the White House.
"Every pathway to a nuclear weapon is cut off," Obama said, adding this provides for extensive inspections. "This deal is not built on trust. It is built on verification."
